Application filed November 22, 1909. Serial No. 529,449.

adapted for use in climbing up .or down pipe whenthe latter is used as a fire escape.

lThemain object of the invention 'is to provide a' device of this character which may be attached tothe feet of the user, which cla'mps or climbers are adapted, uponv an upward movement of the foot, to release from engagement with the pipe, but upon avdownward movement to grip the pipe.

The invention consists inthe details of construction and arrangement of parts set forth in the accompanying specification and more particularly specified in the claims appended.

' For a full understanding of the invention and the merits thereof, and toI acquire a knowledge of thedetails'of construction, reference is to be had to the following description andA accompanying drawing,` inv which: Figure 1 isa view showing my "pe climbers in use; Fig. 2 is a plan view .t ereof opened; Fig. 3 -is a perspective view .of

one of the climbers Fig. 4 is ain edge view.

Corresponding and like parts are referred y to in the following description and 1nd1- cated in all the views of the drawing by thesame reference characters.

Referring to these figures, A designates a pipe of any desired character which, in this instance, 1s supposed to be located against the wall of a'house andto be usedl as a fire esca e. v Mry device consists of a split r1ng,this ring being composed of the semicircular sections 2 and 3, these sections being pivoted to each .other and preferably pivoted to each other closed together, are adapted to surround a pipe, but to fit loosely thereon so that when the sections 2 and 3 are in a' horizontal plane, or a plane perpendicular to the direction of the pipe, the ring formed by the sections will slip easily upon the pipe, but that when the lplane of the'sections is inclined to the hori- 'zontal, the ring formed by the sections will bind upon the pipe andclamp thereon in an obvious manner. The ring formed by these sections hasvsharp interior corners wherebyA when the plane of' the sections is inclined, the interior corners will bite .upon the pipe to prevent slipping of the ring. The ring sections have projecting from theirV free ends. the arms G and 7. Both of these arms are. alike,'except for the fact that one, 6, is Wider than the other. The ends of the arms are upwardly turned, as at 8. The arm'G is provided with the link 9 pivoted in the upwardly'turned end so as to engage over the upwardly turned end 8 of the arm 7 and hold the two arms and the ring sections closed upon the pipe. It is necessary to pro` vide means whereby the climber may be attached to the foot, such means being arranged to give a certain degree of freedom to the foot, and to thisend I have provided the stirrup 10 which is pivoted to the armI 6. This Vstirrup is large enough to receive the foot of the user, and being pivoted, permits of certain lateral freedom of movement of the foot.

The use of my invention will be obvious.

Two of these climbers should preferably be used, one for each foot. It will -be obvious that when the weight of the body rests upon the arms 6 and 7, the ring sections 2 and 3 will be clamped upon the pipe. By rest-ing the weight of the body upon one climber, as above described, and relieving the other climber of weight and raising it or lowering it upon the pipe, then allowing the-weight to come upon the second climber and' relieving the first of weight and moving it down to the second climber, itwill be obvious that the operator may raise or lower` himself upon the pipe with very little difficulty and no danger. The ring sections 2 and 3 being clamped upon tlieApipe by thelink 9it is obvious that there is no danger of the climber be-'` coming released fromthe pipe. The ring sections being pivoted, permit the climbers to be easily clamped upon the pipe when Vwanted` The v'climbers are designed to be kept handy and to be used in case of fire.

My vinvention is simple,` compact, may be easily applied, and is obviously capable of use with 'any pi-pe which may eXtend down the side of a buildin.

y Having thus described the invention, what I claim 15:#

1. A climbing device comprising semicircular sections having pivotal engagement with each other'at one end, the other ends of the sections being provided with outwardly projecting portions adapted to fit against cach other when the ring 1s closed around the pipe, a link engaging over the" .projecting portions of the sections to hold the sections closed, and a stirrup mounted on one of said progecting portlon 'v 2. A climbing device of the character de-Y scribed, comprising semicircular sections pivotally engaged with each other at one end, the other end of each of the sections being provided with an outwardly projecting portion adapted to contact with a like projectin portion of the other section, the ends of sai outwardly projecting portions being turned upward, a link pivoted to one of the upwardly turned ends and Vengaging over the other upwardly turned end, and a stirrup pivotally mountedfon one of Said projecting t portions.
